Checking in on your stocks once per quarter — such as when you receive quarterly reports — is plenty. But it’s hard not to keep a constant eye on the scoreboard. This can lead to overreacting to short-term events, focusing on share price instead of company value, and feeling like you need to do something when no action is warranted.
When one of your stocks experiences a sharp price movement, find out what triggered the event. Is your stock the victim of collateral damage from the market responding to an unrelated event? Has something changed in the underlying business of the company? Is it something that meaningfully affects your long-term outlook?
